The enzymatic properties of two Avicelases, FI-Avicelase and FIII-Avicelase, from Aspergillus aculeatus No. F-50 were investingated. FI-Avicelase had an optimum pH of 5.5, but FIII-Avicelase had a low optimum pH of 2.5. The optimum temperature of both enzymes was 65℃. Both Avicelases were more active on amorphous cellulose, alkali and phosphate-swollen cellulose, and insoluble cellooligosaccharide, but their activities toward CM-cellulose and Avicel were very low. However, both Avicelases degraded Avicel to extents of 31〜47%. Among the nine cellulase components of A. Aculeatus No. F-50, the two Avicelases were essential enzymes for the degradation of crystalline cellulose.
